Significats de several virulence en anglès

We found that acidity is a signal modulating the expression of several virulence factors.

The fungus is endowed with several virulence factors, including capsular polysaccharides that play a key role in virulence.

Compared to mid-log-phase organisms, cells harvested from the stationary phase upregulated genes encoding several virulence determinants and a homolog of hfq.

Several virulence-associated genes were located in a putative pathogenicity island, which was duplicated in the genome.
